North Korea says it has successfully refloated a new destroyer that capsized upon launch last month, with state media reporting the damaged vessel will be moved to a dry dock in a different shipyard for repairs.
“After restoring the balance of the destroyer early in June, the team moored it at the pier by safely conducting its end launching on Thursday afternoon,” a report from the state-run Korean Central News Agency (KCNA) said.
A satellite photo taken by Planet Labs on June 5 showed the formerly stricken vessel righted and seemingly floating in water away from the pier where the disastrous launch took place.
As I recall from an earlier article, the reason that they did the (normally less desirable) sideways launch is because this facility normally works on smaller boats.

l’d bet that they probably have about the minimum required to get the thing out to deeper water.
